Haumarutanga Whaiaro-kati Parahi Valve mo te Paipa Hau
Tauwāhi Tāuta
Ka taea te whakauru i te riu kati-whaiaro ki runga i te paipa hau i mua o te umu, whakamahana wai ranei.
Hua Painga
Pipeline whaiaro kati te haumarutanga a Valve me nga painga:
1. hiri pono
2. tairongo teitei
3. whakautu tere
4. rōrahi iti
5. kore kohi pūngao
6. ngawari ki te whakauru me te whakamahi
7. ora roa
8. Ka taea te whakarite atanga
Mahi: Ki te kore te uara huinga haumaru i te paerewa, kati aunoa i te takirere, tapahia te puna hau. Hei tauira, ka puta te pehanga hau i runga i te pehanga, i raro i te pehanga me te nui o te naianei, ka kati aunoa te takirere. Kia katia te takirere, ka taea anake te whakatuwhera ma te ringa. Mena ka mutu te hau, te tuku hau rerekee, ka taka te ngongo rapa, aha atu, ka kati aunoa te takirere kia kore ai e pakaru te hau.
